After decades of rapid progress, classical computer technologies are increasingly reaching their limits. The steadily growing demand for computing power calls for new approaches. Technologies based on the laws of quantum physics are expected to play a central role in this context. Quantum computers can achieve computational performance far beyond that of classical systems and thus provide key impulses for the development of new materials, chemicals, or secure communication pathways. In recent years, the field has made tremendous progress: processors with several hundred qubits already demonstrate the potential of this technology. However, scaling up to thousands or even millions of qubits remains one of the greatest challenges on the way to practical applications. Quantum computing is therefore entering a decisive phase. ML4Q focuses its research on developing novel quantum hardware and software, with particular emphasis on disruptive technologies that are still in their early stages but have the potential to fundamentally shape future developments.

ML4Q’s activities encompass four qubit platforms at different stages of development: superconducting, Rydberg, spin, and topological qubits. Building on previous breakthroughs, the teams pursue goals such as developing new algorithms for quantum processors, improving error correction and hardware stability, creating interfaces for data exchange between and within chips, and exploring entirely new qubit platforms.

Beyond advancing research, ML4Q also promotes the development of a vibrant quantum region. With state-of-the-art infrastructure, outstanding young talent, and three planned key institutions – the “Training and Career Center,” the “Center for Equity, Diversity and Inclusion,” and a central hub for software development and data management – a dynamic network for the quantum research of the future is emerging.
